Back Boxes, Breakaway Boxes & Blanks
FAQs
Back boxes (also called pattress boxes) are enclosures mounted into walls or on surfaces to house electrical outlets, data sockets, or structured cabling modules. They provide a secure fixing point for outlets, protect cabling terminations, and ensure a neat, safe finish for wall mounted devices.
Flush mounted back boxes are installed into solid walls, leaving outlets flush with the wall surface.
Surface mounted pattress boxes are mounted on the wall surface, ideal for retrofitting where chiselling into walls isn’t possible.
Cavity wall boxes are specially designed for plasterboard/drywall, with lugs or clamps to secure them into hollow walls.
Blank faceplates are used to cover unused wall box openings safely and neatly. They are often fitted:
- To cover spare outlets for future expansion.
- To provide a tidy finish where a module has been removed.
- To maintain compliance with electrical/fire safety by sealing unused back boxes.
Accessories include:
- Extension collars to increase the depth of a back box to fit larger modules or accommodate extra wiring.
- Breakaway boxes to allow flexible cable entry and custom cut-outs to suit different installations.
- Cable management trunking that provides structured routing for cables from the back box to other outlets, ensuring neatness and protecting against damage.
